汽包锅炉实现低负荷脱硝的烟气升温系统

A Gas Temperature Rising System of Drum Boiler Denitration Achieve Under Low Load

一种提高锅炉SCR反应器入口烟温的系统(Gas temperature Rising System,以下简称GRS),以满足锅炉低负荷和/或大气温度低造成SCR入口温度低无法投用脱硝系统时提高烟气温度的需要,从而实现在各种负荷条件下锅炉脱硝系统的正常投用。本系统适用于亚临界和超高压的汽包锅炉,包括自然循环汽包炉和强迫循环汽包炉。

A system which can increase the gas inlet temperature of the boiler SCR reactor （Gas temperature Rising System,hereinafter referred to as GRS）, in order to meet the need to increase the gas temperature when low boiler load and/or low atmospheric temperature lead to the low SCR inlet temperature which cause the denitration system can＇t putting-in-service.The GRS can make the denitration system putting-in-service under various load conditions.This system is applicable to the subcritical and ultrahigh pressure drum boiler, including natural circulation and forced circulation drum boiler.
